I'm writing an OData consumer in c#. I can successfully delete an entry, but for some reason it simply hangs / freezes on GetResponse() when I try to update. It even ignores my timeout. Below is my test code. Any intelligent suggestions?
XDocument doc = XDocument.Parse(
@"<?xml version=""1.0"" encoding=""iso-8859-1"" standalone=""yes""?>
<entry xml:base=""http://localhost/odata/service.svc/"" xmlns:d=""http://schemas.microsoft.com/ado/2007/08/dataservices"" xmlns:m=""http://schemas.microsoft.com/ado/2007/08/dataservices/metadata"" xmlns=""http://www.w3.org/2005/Atom"">

HttpWebRequest request =
(HttpWebRequest)HttpWebRequest.Create("http://localhost/odata/service.svc/SimpleTests(7)");
request.Method = "PUT";
request.Accept = "application/atom+xml";
request.Timeout = 1000;
request.ContentType = "application/atom+xml;type=entry";
using (var writer = XmlWriter.Create(request.GetRequestStream()))
{
doc.WriteTo(writer);
writer.Close();
}
using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
{
}
After fiddling around with Fiddler, I came up with the following solution, which works. The part that seems to solve the problem is specifying request.ContentLength. I don't know of a simpler way to get the length, so feel free to comment if you do.

A PUT request does not return any content other than a HTTP code (204 - No Content) for success.
See this part of the OData spec for details.
